If you’re looking to upgrade your home appliances and add Siri control, then HomeKit is a key feature you’ll want to look for when buying new hardware. The number of HomeKit-compatible smart thermostats is continuing to grow with Honeywell’s Lyric Round Wi-Fi Thermostat (2nd-gen) as the latest to hit the market.

Among competing thermostats, the basic premise is the same: Wi-Fi connectivity lets you remotely control heating and cooling from mobile apps, and intelligence using location and the Internet let you add some home automation. The pay off is potentially a lower energy bill and the cool factor of controlling the temperature with Siri.
